It used to seem like anyone who worked online could make a lot of money. Although this was not true for everyone, things have changed and there is more competition online so making money is not so easy. However, there are still ways that it can be done and marketing is a very important part of it.

Website
Many people feel that having a website is a crucial part of their business. They feel that they need to be able to tell people about what they do, have their contact details public and generally be part of the internet. Although they are right, there is more to it than just having a website. Having a website is great, but you need to make sure that people know it is there and that they visit it when they need to. This means that you need to use online marketing. You will need to make sure that search engines know that your site is there by registering with them and see if there are any free directories you can list on as well. You will need to keep your site up to date and adding new content can be a way to get it higher in search engines, so adding blog articles or just extra pages to the site can be worthwhile.
Advertising
Many people pay to advertise online. There are different ways to do this, such as banner advertisements or similar adverts, pop-up adverts, text links in relevant articles and things like that. It can be an effective way of bringing attention to the goods and services that you are selling but it is expensive. You need to very carefully calculate whether it is worth doing and whether the extra income you make covers the costs and still gives you some profit as a result.
Others Websites
It can a good idea to sell your products through other websites. They will take a commission but you may be able to put them up for sale for free or for a very low cost. You will have to adjust the sale price to allow for these costs, but it can be better than your own website as you will not have to pay for domain, hosting or marketing as they will do all of that. Customers may trust buying things from that site more than buying things from an independent website as well.
Social Media
Social media is growing massively and most people use it to promote their products in addition t other forms of marketing. It is possible to start off doing this for free, but if you want to grow you may have to pay to advertise using it. It is well worth being very active, responding to comments and queries and being helpful and friendly as this will enable you to grow quickly with a good reputation. By getting your name known and getting a good reputation you will be more likley to be able to sell things and make a profit.
